Analysis of Spatial Heterogeneity of Soil Available Nutrients in Riparian Zone of Bohe and Jinghe River
Soils in Bohe and Jinghe River riparian were selected as samples.The soil organic matter,available N,available P and available K content under different types of vegetation were measured.Spatial distribution and statistical characteristics of soil nutrients of two riparians were analyzed by using the geostatistics.The results showed that variations of the soil organic matter,available N of Bohe river were greater than those in Jinghe river,variation of soil available P and available K was smaller.Vertical distribution rules of the soil available nutrients were characterized as that soil organic matter and available nitrogen content decreased with the increase of depth.Horizontal distribution rules of soil available nutrients demonstrated that the mean content of soil available nutrient was lower with the increase of distance from Ebinur lake.Overall,the soil available nutrient contents in Bohe river riparian zone were higher than those in Jinghe river,and the spatial heterogeneity of soil nutrients in Jinghe river was smaller.
